glsl: Move is_builtin flag back to ir_function_signature.

Browse Source 
This effectively reverts b6f15869b3.

In desktop GLSL, defining a function with the same name as a built-in
hides that built-in function completely, so there would never be
built-in and user function signatures in the same ir_function.

However, in GLSL ES, overloading built-ins is allowed, and does not
hide the built-in signatures - so we're back to needing this.
